FAN-GOVERNOR.

. SPECIFICATION forming part of Letters Patent No, 700,511, datedMay 20, 1902.

Application filed my 5.1901. Serial M61092. (No model.)

The object of my invention is to provide a simple and readily-operated fan-governorlof that class in which the governor can'be ad-j justed orset for different rates of normal speed, thereby enabling the time ofthe music to be varied in accordance with the requirements of each piece and also enabling the time to be changed while the music-box is in operation -thatis, during the playing of the music.

The invention will be fully described hereinafter and its novelfeatures pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which--- 1 Figure 1 is a side elevation, partly in section, of one form of my improved governor and the parts directly connected therewith.

same substantially on line'i616 of Fig. 7, and Fig. 7 is a plan with 'parts' in section on line 77ofFig.6.

As shown in Figs. 1 to 4:, the franifefiofthe governor has upper and lower brackets 6 and 7, respectively, the lower bracket having jonrnaled therein the shaft 8, .upon which is mountedthe pinion 10, throughjwhich motion is imparted to the shaft 8 from thespringmotor by means of ajsuitable gear-wheel. On

the same shaft Sis also mounted a gear-Wheel 9, engaging a pinion 11 upon a shaft 12, which also carries a worm-wheel 13. This wheel is in engagement with the threads of a worm 14, journaled about a vertical axis in suitable bearings in the brackets 6 and 7. The shaft Fig. 5 is'a. side elevation of anotherform of my inven-, tion. Fig. 6 is a sectional elevationrof the attached one end of a coiled spring 17.

is connectedat its upper end loosely with the of the worm at the same time forms the governor-shaft and has rigidly connected therewith a frame 15, preferably of rectangular shape, the said frame having pivoted to it at the periphery the wings 16 of the governor. The pivots of these Win gs are indicated at 16*. Each wing is provided at its pivot end with an extension or lug 16 and at the other end with a slot or slideway 16. To the lug 16 is The other end of said spring is secured to the free end of an arm 18, having a pivotal connection with a pin. 19, which is adapted to slide in the 'slot 16. 'or substantially so, with respect to the pivot 3 .oftal connection with a bell-crank lever 20, ful- The direction of this slot is radial, 5 The other end of thearm 18 is in pivorumedat 20 upon the wing 16 and provided 22, which is movable vertically upon parallel bars 15*, forming part of the frame 15. This slide also engages the shaft of the worm let jected from a normally stationary rod 23.

This rod has guided vertical movement in a sleeve 24;, carried by the upper bracket 7, and v operating-lever 25, fulcrumed at '25 upon a suitable support orfpost 26', rising from the bracket 7. Upon the shaft of the worm 14: is aalso'seouredthe stop-arm 27, adapted to be engaged by a screw'or other suitable projec- 5 tion to start and st 0p;tlie,motor in the well I known manner. Preferably the stop-arm 27 is capable of ,a slight yielding movement inr dependently of the spindle of the worm 1 1,, being heldin frictional engagement therewith 9 by means of a coiled spring 28." r I It will be understood thatin operation as long as the lever 25'remains in the same po= sition the governor will work in the same way as in the ordinary music-boxes. By actuating the lever 25 the grooved collan22, and with it the slide 22, will be shifted up ordown lengthwise of the governor spindle. This movement through the medium of the grooved collars 21 en a in the ins 2O will cause too D D b p the bell-crank levers 20 to swing on their fulcrums 20 and will thus move the pins 19 and the ends of the springs 17 attached thereto inward or outward relatively to the rods 15. Assuming the tension. of the springs 17 to remain equal, it will be obvious that by such a shifting movement of the spring ends the purchase or leverage of the springs and the resistance they oppose to the centrifugal movement of the wings will be varied, and consequentlythe governing action of the apparatus will be diiferentthat is, if the lever 25 is in the up position (shown in Fig 1) the governor will regulate the speed of the springmotor for a predetermined number of revolutions. Should the lever 25 be thrown fully down, the motor would again rotate at a practically constant rate of speed; but this rate of speed would be different from that obtainiug in the first case. To each intermediate position of the lever and of the slide 22 will correspond an intermediate rate of normal speed. It will be obvious that the speed may be changed, not only before set-ting the mechanism in motion, but just as readily while the music is being played, without injuriously affecting any part of the governor. The invention therefore provides simple and efficient means for changing the normal rate of speed of the motor both while it is at rest and during its operation.

Another form of my invent-ion embodying the same principle and presenting the same advantages is shown in Figs. 5, 6, and 7. In these views the frame 5, with its brackets G and 7, and the driving-wheels 9, 1O, 11, and 13 have been omitted, it being understood, however, that these parts are exactly the same as in the construction first described. Similarly the means for shifting the governor or for adjusting the normal speed are the samethat is, there will be employed a lever 25 with a rod 23, havinga projecting pin 23, exactly as shown in Fig. 1. This pin will engage in a groove 22 of a cross-bar or slide 22, movable vertically upon the spindle of the Worm 14 and upon the parallel bars 15,Whieh form part of the frame 15. Adjacent to the bars 15 the slide 22 is formed with arms or lugs 21, which engage a sleeve 21*, movable vertically 011 the bars 15 From each of the sleeves 21 is projected a pin 21, which works in a vertical slot 16 of the corresponding wing 16 and in a curved slot 20 of an arm 20, fulcrnmed at 2O upon the wing 16. At its upper end said arm carries a pin 29, which passes through a segmental slot 16 of the wing 16 and carries a weight 29. The springs 17 are connected with the ends of the wings l6, and no provision is made for shifting the springs, as in the construction first described.

It will be understood that as the slide 22 is moved up or down by means of the lever 25 the pins 21 will cause the arms 20 to swing on their pivots 20 carrying the Weights 29 nearer to or farther away from the bars 15 about which the wings 16 swing. This will increase or diminish the resistance which the said arms oppose to rotation, and thus the speed of the mechanism will be regulated.

.It will be understood that this regulation is readily effected while the mechanism is in motion.

Idesire it to be understood that in both constructions I employ shifting means movable upon the wings toward and from the pivots of the wings, and by changing the position of said shifting means I vary the location of the center of gravity, and thus increase or decrease the momentum of the revolving wing.

In the construction in which the springs themselves are shifted or adjusted the center of gravity is obviously varied at the same time, since the springs virtually form weights. In other words, in the construction illustrated in Figs. 1 to 41-, inclusive, there is obtained a double action by adjusting the springs, said action being due partly to the fact that by shifting the springs on the wings the center of gravity is altered, and, second, the purchase or effective energy of said springs is also varied, as above set forth.
